Potpourri_6 TS-Linux Consider that a system running TS-Linux has a periodic timer starting at t = 0ms with a period of 25ms. A firm timer with a system-wide overshoot parameter of 5ms is also available for use. A user schedules an event A with firm timer expiry at t = 47ms.  The user also schedules another event B with firm timer expiry at t = 155ms. Remember that when a user schedules a firm timer expiry at t = x on a system with an overshoot parameter y, the one-shot timer interrupt will be scheduled for t = (x + y). Ignore any system calls/external interrupts. Assume that the kernel is never executing a critical section and that there are no other tasks to be scheduled. What would the duration between fielding the two timer events A and B be? Explain succinctly.

Potpourri_7 LRVM Consider an application using the LRVM library.  A first transaction in the application uses multiple set_range calls and commits with the “no_flush” mode in its end_transaction. A second transaction in the same application modifies the *same data blocks* modified by the first transaction and commits with a “flush” mode in its end_transaction.  (Answer True/False with justification; no credit without justification): The above scenario will result in LRVM doing redundant I/O for the first transaction followed by the I/Os for the same data blocks for the second transaction.
